题目描述

Maxim loves sequences, especially those that strictly increase. He is wondering, what is the length of the longest increasing subsequence of the given sequence aa ?

Sequence aa is given as follows:

  • the length of the sequence equals n×tn×t ;
  • (1<=i<=n×t)(1<=i<=n×t) , where operation means taking the remainder after dividing number xx by number yy .

Sequence s1,s2,...,srs_{1},s_{2},...,s_{r} of length rr is a subsequence of sequence a1,a2,...,ana_{1},a_{2},...,a_{n} , if there is such increasing sequence of indexes i1,i2,...,iri_{1},i_{2},...,i_{r} (1<=i_{1}<i_{2}<...\ <i_{r}<=n) , that aij=sja_{ij}=s_{j} . In other words, the subsequence can be obtained from the sequence by crossing out some elements.

Sequence s1,s2,...,srs_{1},s_{2},...,s_{r} is increasing, if the following inequality holds: s_{1}<s_{2}<...<s_{r} .

Maxim have kk variants of the sequence aa . Help Maxim to determine for each sequence the length of the longest increasing subsequence.

输入格式

The first line contains four integers kk , nn , maxbmaxb and tt (1<=k<=10; 1<=n,maxb<=105; 1<=t<=109; n×maxb<=2107)(1<=k<=10; 1<=n,maxb<=10^{5}; 1<=t<=10^{9}; n×maxb<=2·10^{7}) . Each of the next kk lines contain nn integers b1,b2,...,bnb_{1},b_{2},...,b_{n} (1<=bi<=maxb)(1<=b_{i}<=maxb) .

Note that for each variant of the sequence aa the values nn , maxbmaxb and tt coincide, the only arrays bb s differ.

The numbers in the lines are separated by single spaces.

输出格式

Print kk integers — the answers for the variants of the sequence aa . Print the answers in the order the variants follow in the input.
